To all whom 'it may concern.

Be it known that I, TnoMAs CARRoLL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description. This invention relates to improvements in registering-and recording machines and has more particular relation to improvements in machines used iniconnection with checking systems employing checks, sales slips or ;receipts upon which-the transactions are tobe recorded by the machine.

One of the principal ob ects of the' pres-.

\ ent invention is to provide improved printing devices in connection with machines of the character above-mentioned, more es ecially as relates to the operation of the ta le carrying the sales slip, and to certain devices in connection with an identification key. Certainother novel constructions are also described and shown as forming art of the development of the entire macine but only those improvements relating to the printing devices are claimed herein.

With-these and incidental objects in view, the invention consists in certain novel features of. construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment'of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

The present invention covers improvements on the type of machine included in my present ending application No. 75,713 filed Septemher 20, 1901.' 1

Described in general terms the machine of setting levers or elements, which when moved, position suitable racks over which the counter is subsequently drawn and thereby operated; It will thus be seen that int-his partici lar .v formtof register or' recorder-the ameuntfto be accounted depends upon the positions 01? at the time the operating handle is' rotated to give the counting mechanism a vertical movement. If all of the setting'levers are in a normal or zero posi'e tion the machine cannot be operated, but I when any one of said levers is adjusted to a position'oplposite a number on the scale plate shown in ig. and the rack. connected .to said setting lever is movedfltoaposition in which a certain number of its teeth will project into the '13' the machine is unlocked path of movement of one of the counter pinions and thus actuate the latter when the counter is moved over the rack. The power which is applied to the operating crank handle 22 is transmitted through suitable gears 23 and 2. to the rotation shaft 24: which extends across the rear of the machine and is journaled in the side plates of the frame 1. All of the various'parts of the machine are driven from this rotation shaft 24 which will be hereinafter more particularly described.

The setting and registering mechanisms of the machine are mo e clearly illustrated in Fig. 2 and by reference to this ligure it will be seen that each of the setting levers 2t is connected to a disk or plate 25 which is journaled upon a transverse shaft, 21. Each of the disks 25 is formed with a series of rack teeth 25, and is provided with a toothed locking plate 25". The gear teeth of the disks are at all times in mesh with rack teeth 26 upon the rear edges of tour vertically sliding rack bars 27; these bars being also termed upon the front edges with registering rack teeth 28 with which the counting pinions cooperate. The bars 27 are mounted in suitable slotted guide bars 27 of the main frame whereby they are held to accurate vertical movements. It will be seen from the above that these registering rack bars will always occupy positions having a registering valuation corresponding to the positions of the settin levers 21. Thus, if one of the levers 21 is moved to a position representing five cents on the scale plate, the corresponding rack bar would be moved to a position in which five of its rack teeth 28 would be brought into the regular operating path of the particular pinion of the counter corresponding to the denominational value of the bar operated. The connections hes tween the operating handle 22 and the mov- 'friction rollers 30 upon each end.

able counter are such,that the counter is first moved downward over the rack teeth 28 to actuate the counter wheels, then disengaged from said teeth and moved back to its normal upper position.

During the return movement of the counter the counter pinions are not in engagement with the rack teeth and during this time the transfer is effected. To this end the counter complete is supported in and carried by a frame 29 which has two anti- The counter-frame, carrying the counter, is vertically slidable in a rock frame which is formed of the two parallel, vertical sidearms 32 which are connected at their lower ends by a tie-bar 33. The inner side of each vertical side-arm has torme'dtherein, a slideway or channel 31. The anti-friction rollers 30, of the counter frame, run in these slide Ways, and in this manner the counter is guided vertically in its reciprocations. A cross-shaft 3 1 passes llllQllO'l! hearings formed in the upper ends of the vertical side-arms 32, whereby the rock-frame carrying the counter, may be swung a limited distance toward the rear and back again to its normal position shown in Fig. 2.

The machine is arranged, when operated, first, to swing the counter a short distance toward the rear in order to bring the teeth of the counter-pinions in a vertical line with the registering rack-teeth. The counter is then moved downward so as to pass over the registering rack-teeth and be thereby operated. Third, the counter is swung toward the front of the machine out of engagement with the registering rack-teeth and finally the counter is moved upward to its normal position.

For convenience in setting or adjusting the levers 21 to the desired positions, they are given different lengths and are provided with small indicators 35 (shown in Figs. 1 and 2.) Each indicator is connected to its respective setting lever through its segment 25. The unitsot-cents segment is secured rigidly upon the pivot-shaft 2.1. (See Fig. 8.) 111 like manner the units-ot-cents driving segment 36 is secured upon said shaft and is always in mesh with the indicator pinion 37, secured to the units-of-cents indicator 35. The tensot'-cents segment 27 is secured upon the right-hand end of a sleeve 38, and upon the left-hand end thereof is secured the tens-ot-cents driving segment 36. In like manner the units-ot-dollars indicator segment 36 and the tens-ot-dollars driving segment 36 are rigidly connected with their respective segments 25 through the sleeves 38 and 38". Through the sleeves 4'0 and the pinions 37, 37", and .37, which are all concentric and turn upon the indicator shaft 35), the indicators are geared to their IUSPQCtlVO, driving segments. Under this construction it results that when a setting lever is moved, its respective indicator is correspondingly moved.

As shown in the drawings there are four amount or value printing-wheels, 11, 4:1, 41." and 41., and these are connected in a well known manner through sleeves 12 and the pinions 43 with the. respective driving seg ments 3(3, 36, 36" and 36 (Figs. 1,2 and '10).

It results from the construction, just described, that the movement or adjustment of any setting lever directly and correspondingly moves the indicators 35, theregistering rack bars 27, and the value printing- Wheels. The indicators, therefore, form a convenient means for ascertaining it the various parts, just enumerated, have been properly adjusted so as to register and record the desired amount, because the operator can simply. adjust the setting levers until the indicators show the amount he desires to' register and can then be certain thatthe subsequent turnmg ol the crank 22 w1ll cause career that desired amount to be registered and recorded.

As shown in Fig. 11, each of the firstfour counter or registering-wheels 29, counting from the right, carries a registering pinion 46, which is arranged to engage with its respective racks 28. Each pinlon is secured to the right-hand side of its respective registering wheel, and to the right-hand side of each pinion 1s secured a thin metal disk 47, of a diameter about equal to that of the registering wheel, and finally, to the right-hand side of each disk is secured the ratchet-wheel 48. The purpose of the disks 47 is to keep the registering-racks properly in engagement with the registerin pinions.

Cotiperatmg with the ratchet wheels 48 are the usual spring pressed retaining-pawls- 49 to prevent retrograde movement of the registerin -wheels. Transfer pawls 50 cooperate with the wheels 48 and are pivoted at their lower ends to the rear ends of the transferlevers 51, each of which is pivoted about midway of its length upon a crossshaft 52 which is supported-at its ends in the counter-frame. At its front end, each .of the pawl-actuating levers carries an antifriction roller 53. During the return movement of the counter; that. is, while it is be- 0 ing swung upward to normal position, these anti-friction rollers contact with the fixed transfer-cams 'or projections 54, which are rigidly mounted near the front of the casing of the machine and are arranged in graduated order (see Fig. 7) so that the respective pawl-actuating levers will contact therewith successively and thereby be successively actuated. When so actuated the front ends are swung downward and their rear ends carryin the transfer pawls are swung upwar against the tension of the springs 55 turned to zero. The-trip-pawl holds "the which connect the pawl-carrying levers and the trip-pawls 56. The latter are, as usual, for the purpose of holding the transferpawls in their inoperative positions so that normally they will not engage the teeth of the ratchet-wheels 48, and hence normally will not move the re istering-wheels, and this despite the fact t at all of the pawlcarrying levers are successively actuated at each operation of the machine, and carry the pawls with them, (see Fig, 2.)

By reference to Fig. 7 it will be seen that the cam projections 54 are inclined so that when the counter-frame is in its normal position shown in Fig. 2 the levers 51 have been depressedsufliciently at their forward ends to causethetransferawls to slightly overlap the teeth of the rate et-wheels. This is to prevent the .transfer-pawls falling in back of the ratchet teeth when the trippawls' 56 are operated by the counter being transfer-pawl in inoperative position by reason of the normal engagement of an arm 57 and thereby swing the rear end 0 with the outer one of thetwo notches 58 formed on the rear end of the trip-pawl.

The upper side of the said pawl is provided which it results that when the registering Wheel has made a complete revolution, the trip-pin will strike the operating nose 59 the trippawl downward against the tension of the spring 55 and permit the transfer awl to swing toward the ratchet under the impulse of a spring 61 until the arm 57 drops into-the second or inner notch of the trip-pawl. Each spring 61 is connected at its forward end to the counter frame. The tripping action brings the upper operating end of the transfer pawl into such position that the transferpawl will turn the registering-wheel of next higher denomination one notch, when its respective lever 51 is operated. The stopin 62, one of which is carried by each trans erpawl, is for the purpose of preventing said pawl from being inadvertently or otherwise thrown entirely out of engagement with the ratchet-teeth at the point of the extreme upward travel of 'said pawl which might permit over-throw.

The three registering-Wheels on the lefthand end. of the counter are not actuated directly by the registering-racks and re ceive movement only as it is transmitted to. them from the tens-of-dollars registering wheel. A single pawl actuating lever 51,

' shown in Fig. 6, has pivoted to its rear end a spring-pawl 63 which has three graduated teeth arranged in a manner well known in the art whereby the hundreds-ofedoll'ars re'gistering-wheel 64 is turned one notch whenever the tens-of-dollars wheel 65 has made with the tripping-pin 60 carried by the'tens of-dollarsregistering-wheel and with anf iarm .1

57 on the pawl 63 The three-tined pawl operates so that when the hundreds-ofidollars registering-wheel hasmade a complete revolution, the thousands-of-dollars registering-wheel 66 is turned one notch, and so on up through the capacity of the counter.

InFi 2 and 5 are shown the various devices or giving the counter two motions; that is, its horizontal movements and its vertical reciprocation. Its first horizontal movement, as previously stated, is for the purpose of bringing the registering-pinions 1 46 into the same vertical plane with the ver* tically extending registeringracks. The vertical reciprocation of the counter is for the purpose of causing the registering pinions to pass-downward into mesh or-engages ment with the then-stationary registering-1 rack teeth and over said teeth wher'eby the several registering wheels are turned to 'a greater or less extent according to theiposi 105 a complete revolution. To this end em ploy the usual trip-pawl 56 which coiiperates tion of the setting-levers, and rack bars. When the counter has reached the lowermost point of its vertical travel, the counter is swung toward the front of the machine again, which disengages it from the registering-rack teeth, and then while held thus disengaged it is again moved upward to normal position.

The lateral movement of the counter eliectcd through a horizontal bar or link 67 (Fig. 5) which is pivoted to one of the side arms 32 of the rock-frame in which the counter frame slides. The rear end of the link is bifurcated, forming two lingers (58, which straddle the rotation shaft 24. Secured to one side of the link near its bifurcated end, is an anti-friction roller (32) which slides within a cam-grove (shown in broken lines in Fig. 5) in the disk 71 fast upon the revolution-shaft 24. The coir t' iration of the cam groove is such that as soon as the crank handle is started the counter frame is swung toward the rear to bring the counter pinions into alinement with the registering-rack-teeth, as heretofore described. It is held in this position while the counter frame is moved downward and is then thrown out and toward the front and tlms held during the remainder of the operation of the machine.

The vertical reciprocation of the counter is brought about by the operating-lever 72, which is pivoted between its ends upon a horizontal shaft 73, which is supported in a suitable bracket 74 secured to the frame of the machine. At its rear end the operating lever carries an anti-friction roller 75 which runs within the cam-slot 76 (shown in broken lines in Fig. formed in the disk '7 T, which is rigidly secured upon the rotation-shaft 24. At its front end, the operating lever is slotted, forming two arms 78 which straddle the shaft. 79 of the counterframe. By the means just described the counter is given a vertical reciprocation at each operation of the machine because the configuration of the cam-slot 76 is such as to swing the front end of the ope 'ating lever downward and back to normal. position whenever the crank is turned and this of course causes the counter to slide downward in its ways 31 and then back to normal position.

It will be noticed that most of the parts of the machine which have a regular movement whenever the register is operated, are actuated by means of cam-grooves within disks which are fast upon the rotation-shaft 24. Such a disk, with its cam-groove, is sometimes technically known as a bore cam and it will be hereinafter so designated.

ln'order to aline the setting levers so that they will always stop at a point directly opposite some numeral upon the index plates, and for the further purpose of locking the setting levers and the parts controlled thereby, during the revolution of the crank handle, I provide a series of locking and alining pawls 80, best shown in Fig. 2, 70

and pivotally mounted upon the transverse shaft 73. These pawls are of bell crank formation and the forward end of each is formed into a wedge shaped upturned nose 81 which cooperates with the teeth of its re- 75 86 and the noses of the pawls to normally 5 hold the two separated. The locking frame is formed with an arm 87 which is provided with an anti-friction roller 88. This roller operates 111 the cam groove 89 of a box-cam 8t) which is secured upon the ro- 90 tary shaft 2 t.

The formation of the cam groove 89 is such that when the parts are in their normal positions, shown in Fig. 2, the pawls 80 may be rocked downward by the operation of the respective disks 25 together with the lovers 21. After the levers have been set however, and the rotation shaft moved from its normal position, the frame S5 is cannned downward and forward until the set screws or bolts 86 engage the noses tit), when the pawls S0 become locked against movement thereby also locking the adjusting levers 21. After the registration has been madeand the printing accomplished the pawls 80 are released and allowed to drop by the frame 85 rocking back to a position in which all tension upon the springs 85 is removed. During the time the frame '85 remains in this position, the levers 2i are virtually free and are returned to their normal positions by devices hereinafter described. After-the levers 21 have been so returned the frame 85 is again rocked forward into the" position shown in Fig. 2, whereby the springs 85 are put -under tension to cause the pa wls 80 to properly aline and restrain the leversfll when they are subsequently operated. .lVhen any one of the lovers 21 is actuated and while it is in a position intermediate any two characters on the index plates. the nose 80 will be contacting with the end of its respective screw bolt se, and if an attempt be made to opcrate the machine at this time, the initial downward movement of the frame 85 will 125.

force the alining pawls to become seated between the teeth on the plates 25", and will thus move the lovers 2t to positions in alinement with either one numeral or the other and lock them so. if any one of the levers The frame 85 is provided with 80 I u on the shaft 73 and are fast to a sleeve 179 slot 32 pe at r, looked as no rotation of the shaft 24 can take 21 is held in an intermediate position by the then the operating handle will be place unless the frame 85 is free to move ownward.

As before stated, the setting levers 21 that have been operated are returned to normal position during the latter part of each operation of the machine. This result is efiected by means of pivoted levers 170 journaled connected by a tie bar 1 1 which is provided with a series of antifriction rollers 172, which, when the frame is rocked, engage the res ective levers 21 and force them forward. ,ach of the levers 170 is formed with a nose 173, carrying an anti-friction roller. 174 which cooperates .with a cam 175. These cams are mounted upon the rotation shaft 24 and are so formed as to force the levers 170 forward after the registration and the printing have taken place. When a lever is operated the bar 171 is only forced backward a distance equal to the movement of said lever.

Each of the disks25 is formed with a notch 177 through which projects'a tie bar 178 connectingtwo pivoted levers 179, which journaled upon a transverse shaft 180, as best shown in Figs.

2 and 5,, The tie bar 17 8 is provided with a series of anti-friction rollers 181 which relieve the friction incidental to the contact of the walls ofthe notches 177 in forcing the tie bar rearward. One of the levers-179 is formed at its lowerend with a hook 182 which normally stands in the path of a pin 183, mounted upon the box cam 71. By this means the operating crank handle is locked when all the levers 21 are in'their normal positions. Should one of these levers, however, be moved from its normal position, the levers 179 will be ca'mmed rearward and will thus move the hook 182 out of the path of the pin 183, to unlock the machine.

As will be seen in Figs. 6 and 9, the

counter shaft 45 is extended at one end through the counter frame and through a formed in one of the side pieces. A stop disk 90 is secured to the outer end of this shaft. A stop pawl 91, pivoted on one of th side arms 32, cooperates with a pin 94, mounted upon the disk 90. The pawl 91 is limited in its movements by pin 91 projecting from the same into a recess 91", formed in the side bar 32.

The coiintcr is, of course ,turned to zero when n its upper position, and when inithis position, the pin 94 will contact with the stop arm :93 of thefpawl 91, if the counter shaft is rotated, and thereby arrest the 7 counter wheels tion will move in zero position. This operathe pawl 91 out of its normal posltion aga nst the tension of the sprin 92', which connects an arm 92 of the paw to th'ei-co unter frame. When the counter is ormed on one edge of one of the side arms- 32, as shown in Fig. 9. By this means the counter shaft is locked against any rotation except when it is in normal position in which the disk 90 is free of the flange 90*.

In order to prevent the crank handle from being started or operated while the machine is being turned to zero, I arrange the machine so that the turn-to-zero key or wrench must be inserted through an aperture formed in the side frame, in order to engage said key with the notched end of the counter shaft. Between this a erture and the end of the counter shaft, h wever, is located a pivoted lever 98 which is hung upon the shaft 21*, and is operated as hereinafter described. The front end of this locking lever must, therefore, be swung down, away from the key aperture in the frame before the wrench can h fitted to the end of the counter shaft, and when this swinging takes place, the lever is brought directly in front of a locking pin 100 which is carried by a full stroke disk 101 mounted on the shaft 24, as

shown in Fig. 9. 'A spring pressed pawl 101, cooperates with the disk 101 to prevent any retrograde movement of the same in a manner well known in the art. It results from this construction, as will be readily understood, that the machine cannot be operated while the counter is being turned to ro.-

The aperture 97 is uarded by a movable disk 195, formed wit a hub portion 196, which projects into the aperture 97 and forms a journal for the disk. The disk is limited in its movements by stop pins 197 which roject through slots 198 formed in the dis A coil spring 199 is connected to the disk and the main frame to normally draw the disk into the position shown in Fi 1.- A radial slot 200 is formed in the dis and hub for the passage of a pin 201 mounted on the turn-to-zero key (see Fig. 11). After the key has been partly inserted it mustturned backward slightly before its coupling rojections 200 can enter and become coup ed to the end of the counter shaft. In so turning the key backward, the pin 201 will enga .e the rear wall of the slot 200 and rock the .rfisk 195 sli htly to the rear. When the key is now forced farther inward to couple it to the counter shaft, the disk 195 is released and allowed to return to its normal position by the pin 201 passing free of the slot 200. The turn-to-zero key must now be given a full revolution from its starting position and then turned a slight additional distance in order to bring the pm 201 into alinement with the slot200, to permit the key to be withdrawn. By means of the above described device, it is necessary, in turning to zero, to always turn the key a slight distance in excess of a full revolution. The object of this construction is to assure a complete return of the counter wheels to their zero positions. It will of course be understood that the counter shaft is provided with the usual groove for the reception of the spring pressed pawls on the counter wheels whereby the shaft when rotated will pick up the counter wheels and carry them with it.

In practical use, before the machine is operated, a sales-slip or receipt, for example of the kind shown in Fig. 14, is filled out by the clerk making the sale. In the drawing the voucher is shown as severed from the main sales-slip, but normally it forms an integral part of it, though it is afterward severed by the machine, as will be presently described. Nor is the amount or date printed either upon the main sales-slip or upon the voucher until the slip is placed in the machine. Having filled out the entire sales-slip, usually with a pencil, the operator places it upon the inclined table 102 (shown in Figs. 1 and 3) and lets it slide down until its lower edge rests against the knife support 119 at the lower end of the table. He then adjusts the setting-levers according to the indicators, or if he prefers, according to the scales upon the front of the case of the machine, as shown in Fig. 13. When he has properly set the levers, the indicators should show exactly the amount he wishes to register on the counter and print upon the sales-slip. The operator now turns the crank 22. By means to be hereafter described, the lower end of the table is raised so as to bring the voucher portion of the sales-slip against the type-wheels, whereby there is printed upon the voucher portion the amount of the recorded transaction, the date, a consecutive number, the clerks letter and any suitable word such as Cash, Paid or the like. Then the feed-rollers 104: and 105 are actuated to feed the sales-slip into the machine so far that the voucher portion extends beyond the knife. 106. The sales-slip is then again forced against the type-wheels, whereby the same data is printed upon the main body of the sales-slip, and simultaneously the knife 228 which has meanwhile been raised is actuated to sever the voucher por tion. The movement of the feed-rollers is then reversed so that the main part of the sales-slip is fed back to a position from which it may be readily removed by the operator. The table then swings back to normal position.

As heretofore described, the amount or value-printing-wheels 41, 41, 11 and 411 are directly connected with the setting-levers 21, and they are all supported by the printershaft 108 above the lower end of the table 102.

In order to print upon the voucher and upon the main portion of the sales-slip the month and the day of the sale, I mount the date-printing wheels 109 on suitable sleeves 110 which turn on the printer-shaft 108 as shown in Fig. 10. The date-printing-wheels are therefore in alinement with the amount or value printing-wheels. For convenience in setting the date-printing-wheels, I have secured upon the outer end of each of the sleeves a turn-button 111. These thumb or turn-buttons 111 are formed with a series of apertures 112, through which a locking-pin 113 may be passed to secure the adjusting wheels in their adjusted positions and assure the proper alinement of the several typewheels connected to said wheels. Besides the amount printing type wheels and the date printing wheels, a series of consecutive numbering wheels 202 are journaled upon the nested sleeve 110. These wheels are provided with ratchets 203 which are engaged by-the operating fingers 20 1, of a spring pressed pawl block 205, when said block is rocked. By this construction the consecutive numbering wheels are advanced one number upon each operation of the machine. This block 205 is carried by a pivoted yoke 206 which is journaled upon the outermost sleeve 110 and is connected to an operating sleeve 207. This latter sleeve is provided with a crank 'arm 208 which is connected to an oscillating rack segment 209, by means of a pivoted link 210. As the segment 209 is oscillated upon each operation of the machine, as hereinafter described, the pawl block 205 is correspondingly moved upon each operation of the machine to advance the consecutive numbering wheels one unit.

A series of spring-pressed pawls 211 mounted upon a transverse bar 212 of the main frame, engage the ratchet wheels 203 to prevent any retrograde movement of the consecutive numbering wheels.

The tens-of-dollars printing wheel is provided with a series of dollar signs opposite each numeral and in the space where the zero sign would ordinarily appear so that all amounts printed will appear with the dollar sign before them. The special printing wheel 41 is made fast to the shaft 108 and is provided with a series of similar type characters or words which will be printed beside each amount. In the present instance I have shown this special type wheel as formed with types for printing the word Paid.

A special detachable clerks printing type 214 is constructed with a notched portion 215, as best shown in Fig. 3, so that it may be applied to the shaft 108 at will, whereby different clerks or cashiers may set their own letter of designation for printing when they take charge of the station at which the machine is located. The application of this special clerks printing type is arranged to unlock the machine, and the withdrawal of said type to cause the machine to again become locked. For this construction it will be seen that it is impossible to operate the machine unless some vclerks or 'cashiers designation is in printing position. The key 214, when itis being placed in the machine, is first slipped over the shaft 108 and is then' rocked rearward at its upper end to bring its lower type carrying end into printing position. The type is held in this position by a detachable cover 215, which is placed upon the cabinet against the special type-bar, and is secured in position by a turn button 216. When the bar 214 is forced rearward it' engages a pin 217 of a crank arm or lever 218, journaled upon the sleeve 207. The lower end of the arm 218 is normally drawn rearward by a coil spring 221 connecting it to the main frame. The lower end of the arm 218 cotiperates with a notch 222 formed in a disk 223 mounted upon the shaft 24. By reference to Fig. 4 it will be seen that before the ke of the lever 218 is projecting into the notch 222 and locking the rotation shaft against movement. After the special type 214 has been forced rearward, as shown in Fig. 3, the lower end of the lever 218 is moved out of the notch 222 and the machine thus unlocked. The printing line of types are inked by independent 11)]! pads 224 and 225, of any suitable absorbent material, such as felt, for instance. These pads which are arranged for different colored ink are de- 'upon the movable knife 228. An angular arm 234 is journaled upon the end of the shaft 232 and is connected to one of the arms 230. The lower end of the arm 234 is pivotally connected to i a link bar 235 that is slotted at its rear. end to straddle the shaft 24 and is provided with an antifriction roller 236 which projects into a cam-groove formed in'a disk 237, which is mounted upon the rotation shaft 24. By means of the above construction the ink-pad 214 is forced rearward the lower end carrying frame 227 is drawn back out of the path of the platenduring the period of printing and is again moved forward into this inking position as the operation of the machine is completed.

The knife 228, as before stated, reciprocates against'the stationary knife 106 and arm 244 fast thereto and pivotally connected at its lower end to the link bar 245. This latter bar is slotted at its rear end to embrace the shaft 24 and is provided with an anti-friction roller 246 which projects into a cam-slot 247 of the disk 223, mounted on the shaft 24.

The formation of the groove 247 is such that the initial movement of the disk 223 will effect a slight upward movement of the knife 228 which will force the inking pads against the types that have been adjusted to printing position. N

Later in the operation of the machine, the knife 228 is raised sufficiently to permit the check to be passed forward under said movable knife and over the stationary knife 106, whereby when the said knife. 228 descends, the voucher will be cut from the check and fall into a suitable removable receptacle 250 mounted inthe lower part of the casing and protected by a suitable lockdoor 251.

As has before been stated, the platen or table 102 is given a double printing movement during each operation of the machine, first to print the voucher portion of the check, and then the check itself. For this purpose the table is journaled upon a shaft 252 and is provided with a rigid pendent arm 253, which is best shown in Fig. 4, and is provided at its lower end with an antifriction roller 254. This roller projects into a cam-slot 255 formed in a disk 260, which is mounted upon the shaft 24. The platen proper 257 is mounted near the lower end of the table 102 so that when the latter is raised, this platen will force the check against the types at the printing line. A shaft 258 is journaled in lugs 259 pendent from the table 102 and carries a pinion 260 (see Fig. 4) and two horizontal feeding rollers 104; the latter projecting through suitable, slots formed in the table 102. The' pinion 260 meshes with a rack bar 262 which is held in position in relation therewith by a roller 263 journaled on one of the lugs 259. The bar 262 is pivotally connected to a bellcrank lever 264, which is pivoted upon the main frame as at 265, and is provided with an anti-friction roller 200 which projects mto a cam-groove 207 formed in a cam 208 fastv to the shaft The formation of the cant-groove 267 is such as to feed a printed check forward to have the vougher portion cut therefrom and to bring it into position for the second printing operation and to then feed the printed main check back into a position in which it may be grasped by the lingers of the operator and removed from the table 102. The pressure roller 105, which shown in Fig. 3, is normally disengaged from the rollers 10-1 and is mounted upon a transverse shaft. 270 which in turn is mounted in the forward ends of arms 271 fast to the rock-shaft 252. The shaft 232 carries an arm 272 which is provided at its lower end with an car 274, having a pin 275. A lever 270 is pivoted upon the shaft 252 and is pro vided with a stop ear 27.7 and an car 278 carrying a pin 279 in a similar manner to the car 274. A coil spring 280 is interposed between the ears 278 and 274 and is held in position by pins 275 and 279. The lower end of the level-270 is provided with an anti-friction roller 281 which projects into a canrgroove 282 formed in the disk 283. The peculiar construction above described is to relieve the machine of the work of putting a spring device under excessive tension, After the rollers 104 engage the roller 105, the pressure between the two practically remains the same whether the table 102 is raised or lowered. The spring 280 is only slightly compressed during the time the rollers are in contact and this stress is made uniform during the various movements of the table by moving the spring support 270 correspondingly.

As it is desirable at times to remove the cabinet of the machine, through which the handle 22 passes, I have provided means whereby the handle may be easily removed for this purpose. This means comprises a pivoted spring drawn lever 285 (see Figs. 1 and 16) which is arranged to normally engage a locking notch or channel 286, formed near the inner end of the journal portion of the handle. This inner end of said journal portion of the handle is-beveled so that when the handle is applied in a suitable journal aperture in the machine, it'will raise the said pivoted latch, and by a continued inward movement. permit the same to enter the locking channel. By the above means the handle 22 may be instantly removed by simply raising the lever 285 and drawing the handle out sidewise.

In order to arrest the operating handle 22 in its normal position after it has made two completerevolutions, I provide the gear 23, which makes one revolution upon each operation of the machine, with a segment 288 having a locking notch 289. The gear 23 is also provided with a stop pin 290. A pivoted lever 291 is mounted upon the main frame and is normally drawn downward against a stop pin 292 by a coil spring 293. The lever 291 is provided with an arm 29a which, when the machine is operated, is engaged by the pin 290 to force the rear end of the pawl into the notch 289 to arrest the machine. The wall of the notch 289, as well as the nose of the pawl which enters the same, is constructed on a tangent to the shaft 2% and it is thus necessary after the parts have become locked to move the gear 23 back slightly in order to permit the pawl 291 to drop free of the locking notch.

It will be seen from the foregoing description that the machine is automatically arrested after two revolutions of the operating handle but may be instantly released again by a slight rearward pressure upon the handle.

As has been before stated, the lever 98 is normally locked in a position to prevent the turn-to-zero wrench being applied to the end of the counter shaft a5 to turn the counter to zero. For this purpose the forward end of the lever is formed with a notch 295 into which projects an angular arm 296 forming part of a bolt 297, as best shown in Figs. 9 and 12. The bolt 297 may be controlled by any suitable form of lock mechanism arranged to be operated by a detachable key. VVhenthe parts are in the position shown in Fig. 9, the bolt 297 has been thrown down- Ward to permit the counter to be turned to zero. \Vhen the bolt is thrown in this manner it is also desirable to expose the counting wheels so that a reading may be made from the same before the counter is turned to zero. The counting wheels are normally concealed bya shutter or plate 298 which projects overa sight aperture 299 through which the counter wheels may be viewed. The shutter 298 is pivotally connected to one end of a lever 300 which is pivoted upon the main frame as at 301 and is connected to the bolt 297 by a pin 302. A spring arm 303 is formed on the lever 300 and engages the side of the shutter. 298 to prevent any excessive vibration or rattling of the shutter Enduring the time the same is being shifted.

VVhen the bolt' 297 is moved downward the lever 300 is rocked on its fulcrum and the shutter 298 moved upward at its outer end. After this end has moved up a certain distance it contacts with a stationary pin 304 on the main frame and thus arrests this end of the shutter. As the lever 300 continues to operate the pin 304C becomes a fulcrum for the shutter with the result that the opposite end of the same is then raised until it contacts with the pivot pin 301. The shutter is moved downward in substantially the same manner, its lower edge contacting with stationary lugs 305 mounted on the main frame. These latter lugs also support a suitable transparent guard plate 306 which projects over the aperture 299.

While I have shown no cash drawer n connection with my present invention 1t w1ll be readily understood that I can apply a cash receptacle and operate the latchof the same from the operating handle in any well of bills or checks and are usually paid by presentation at the oflice, together with the amount of the bill. Such checks or b1l1s are inserted in the machine and the voucher cut therefrom and the bill at the same time stamped Paid so that it may be returned to the person making the payment as a receipt.
